Thermodynamics of Black Holes in Horava-Lifshitz Gravity
Rong-Gen Cai, Li-Ming Cao, Nobuyoshi Ohta
By using the canonical Hamiltonian method, we obtain the mass and entropy of the black holes with general dynamical coupling constant in Hoř ava-Lifshitz Gravity. Regardless of…
Dynamics of intersecting brane systems -- Classification and their applications --
Kei-ichi Maeda, Nobuyoshi Ohta, Kunihito Uzawa
We present dynamical intersecting brane solutions in higher-dimensional gravitational theory coupled to dilaton and several forms. Assuming the forms of metric, form fields, and di…
Shear Viscosity from Gauss-Bonnet Gravity with a Dilaton Coupling
Rong-Gen Cai, Zhang-Yu Nie, Nobuyoshi Ohta +1
We calculate the shear viscosity of field theories with gravity duals of Gauss-Bonnet gravity with a non-trivial dilaton using AdS/CFT. We find that the dilaton filed has a non-tri…
Black Holes in the Dilatonic Einstein-Gauss-Bonnet Theory in Various Dimensions III -- Asymptotically AdS Black Holes with --
Nobuyoshi Ohta, Takashi Torii
We study black hole solutions in the Einstein-Gauss-Bonnet gravity with the dilaton and a negative ``cosmological constant''. We derive the field equations for the static spherical…
